Checked against the Google Merchant Center product data specification.

Google Merchant Center checks every product in your feed against its product data specification. Missing required attributes, wrong formats, invalid identifiers or inconsistent prices lead to warnings and disapprovals, and disapproved products cannot appear in Shopping results or ads.
Finding these problems only after uploading wastes days: Merchant Center needs time to process a feed, and repeated issues can lead to account warnings. Validating the file before upload catches most problems in seconds.
Common issues include missing brand or GTIN, prices without a currency, invalid availability values, image links that do not load, titles that are too long and missing shipping information for certain countries.
Merchant Center rejects or limits products with missing attributes, bad formats or broken images β and you often find out only after the feed is processed. Validating first lets you fix every problem in one pass.
Fix errors first β they cause disapprovals. Warnings can limit performance but usually do not block products. After fixing, validate again until the errors are gone.
Some checks, such as whether the price matches the live page, can only be confirmed by Merchant Center itself, so keep an eye on its Diagnostics after upload.
An electronics retailer in Poland exported a new feed of 1,200 products from its warehouse system.
The feed validator found 140 products without a brand, 60 with prices missing the currency code and 25 with invalid availability values such as "yes". The team fixed the export mapping rather than editing rows by hand, re-validated until the errors were gone, and then uploaded the feed β avoiding a wave of disapprovals in Merchant Center.
Errors usually cause disapprovals; warnings can limit how often products show but do not block them.
No. Merchant Center also checks landing pages, prices and policies, so review its diagnostics after uploading.
